Hi Humbertogo
Make a block with a circle and run this
Sub BlockEdit()
Dim oBlocks As AcadBlocks
Dim oBlock As AcadBlock
Dim oBref As AcadBlockReference
Dim Ent As AcadEntity
Dim V, BlockEnt As AcadEntity
Set oBlocks = ThisDrawing.Blocks
ThisDrawing.Utility.GetEntity Ent, V, "Pick a blockreference:"
If TypeOf Ent Is AcadBlockReference Then
Set oBlock = oBlocks(Ent.Name)
For Each BlockEnt In oBlock
If TypeOf BlockEnt Is AcadCircle Then
BlockEnt.radius = BlockEnt.radius * 2
BlockEnt.Color = acRed
Ent.Update
Exit For
End If
Next BlockEnt
End If
End Sub
I remember wanting to explode blocks to find the arcs and the lines, if you need that I have some stuff
